Strelka (Russian: Стрелка) is a computer chess engine for Windows, developed by Yuri Osipov and released in May 2007. In total five versions of the program have been developed with the latest 5.5 version, released in May 2012, running only on a single processor core. The engine is named after the Soviet space dog of the same name.[1] Strelka's achievements has been considered controversial, due to the disputed originality of its source code.
Strelka has been one of the strongest chess programs in the world according to the rating lists published by "Computerchess.org" and "husvankempen.de", entering the lists in late 2011[2] and climbing the ranks, taking second place in the 40/4 blitz rating list by December 2011[3] and seventh place in the 40/40 rating list by April 2012.[4]
After late 2012, Strelka dropped to the fourth place in 40/4, surpassed by the Critter,[5] Komodo, and eventually Stockfish.[6] Strelka fell out of top twelve in 40/40 rating by early 2015.[7]
